SASH-CORD FASTENER.

EPECIE'ICATION forming part of Letters Patent No. 345,878, dated July20, 1886.

Application filed December 5, 1885. Serial No. 184,812. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD THOMAS BRAD- BURY, of Mahanoy City, in thecounty of Schuylkill and State of Pennsylvania, have invented a new andImproved Sash-Cord Attachment, of which the following is a full, clear,and exact description.

The object of my invention is to provide a cheap and practical devicefor attaching sash- IO cords to window-sash, and which will permit theeasy detachment of the cord from the sash and its easy reattachmenttothe sash again in case the window is to be removed from the window-frameand replaced.

The invention consists in forming the device with sharp edges to embedin the window- ,sash, so the device cannot become detached from theframe of its own accord; and the invention finally consists ofthespecial construetion of the attachment and its parts, all ashereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate eor-2 responding parts in all the figures.

Figure 1 is a sectional elevation of a part of a window-sash, showing myinvention applied to the same, theattachment being shown in sectionalelevation. Fig. 2 is a front eleva- 0 tion of the edge of a window sashand cord having my new attachment applied thereto, and Fig. 3 is asideelevation of the attachment.

A represents my new sashcord attachment applied to the sash-cord B andwindow-sash 5 G, the latter being formed with an open groove at c, whichterminates in an enlarged recess at c, which recess is adapted toreceive the attachment A and cord B. The recess 0 is larger than thegroove 0, so that by forming 0 the said recess 0 the shoulders c c" areformed at the bottom of the groove 0, and the recess a is by preferencemade somewhat deeper than the groove 0 to form the shoulders c in thesash.

The attachment A is composed of the two parts or sections a a. The parta is made 'hollow to receive the end of the cord B, and the part a actsto wedge the device fast to or upon the cord B. The part a, besidesbeing made hollow,is formed with a lip, e, which is made sharp, and isadapted to engage with orembed itself in the shoulder 0 formed in thesash. The part a of the attachment is composed of the slightly taperingor wedging halfround shank 13, that fits in the cavity of the main parta, and the upper portion or head, 1". This head 2" is made larger thanthe cavity of the part a, to prevent part a from dropping through thepart a, and it is formed with the flange i and with the sharp edge 1;,that is adapted to engage with or embed itself in the shoulders c of thesash, asillnstrated in Figs. 1 and 2. The inner surface of the part a isserrated or formed with teeth '6 and at its lower end it is formed withthe lip i, for look ing the part a within the main part a, as shown inFig. 1.

In use the end of the cord will simply be passed through the main parta, and then the part a will be forced into the cavity of the part aalongside the cord. This will firmly wedge the cord in the part a, andas the lower end of the part a passes the lower end of the main part athe elasticity of the cord will force the part a outward sui'iicientlyto cause the shoulder or lip i to engage with the lower end of the mainparta, thus securely locking the device upon the cord. The attachmentbeing applied to the cord,in order to apply it to. the sash forconnecting the cord and sash, the attachment has simply to be dropped orpushed into the recess 0' of the sash,when the weight of the sash uponthe sharp edges of the attachment will cause them to become embedded inthe sash, sothat they effecta perfectly reliable and secure connectionbetween the attachment and sash, and in case the window is to be removedfor washing or for other purposes the cord has not to be untied, as isnow the common practice, but the attachment A has simply to be slightlylowered in the recess c and then withdrawn from the recess, whichentirely detaches the window-sash from the window-cord, so the sash maybe removed with very little trouble and delay, and it may be as easilyreplaced.

In some cases the attachment may be used for attaching a weight to thecord B, and for this purpose I form the main part a with the shoulder j,which is on about the same plane as the flange i of the part a, as shownclearly in Figs. land 3, so that a ring, hook, or other device havingthe Weight attached to it may be suspended from the shoulder and flangeof the attachment.

I am aware that a prior sash-cord fastener has been formed of a bodyportion having a vertical cord-aperture and a toothed shoulderedwedge-shaped key Within said aperture for clamping the cord, and I donot claim such as of my invention; but I am not aware that suchfasteners have been provided on theirupper faces with sharp points oredges to engage shoulders at the base of an open cord-groove. The objectof this construction is to avoid making a vertical bore in the sash toconnect the cord-groove with the fastener-recess,as was necessary inorder to use the fastener above referred to.

Having thus described my inventioawhatl claim as new, and desire tosecure by Letters Patent, is

l. The combination, with the part a of a sash-cord fastener having thecord-aperture and the penetratingpoint e on the upper face, of thewedging-section i, having its upper end projecting above the part a andbeveled to form a penetrating point or edge, i substantially as setforth.

2. The combination, with the part a, provided with the cord-apertu reand the penetrating-point e,having ashoulder, j, at its base, of
